Description

Technical Field

[0001] The invention relates to the technical field of electric power systems, in particular to a cement pole maintenance and straightening device. Background Art

[0002] As an important part of the power transmission network, cement poles are widely used in towns, industrial and mining areas, rural areas and other areas. However, since they are basically installed in the wild, the environment is complex and affected by many factors. For example, severe weather such as heavy rain and strong winds may exert a strong external force on the poles, loosening the foundation and causing the poles to tilt. In addition, long-term rain erosion, soil erosion and changes in geological conditions, such as ground subsidence and landslides, will also affect the stability of the poles, causing them to gradually tilt. The problem of pole tilt is relatively common.

[0003] After the electric pole tilts, it can generally be kept in use by straightening operations. For example, the patent with publication number CN111021815A discloses an electric pole straightening device for electric power engineering construction, including a first base plate, a second base plate, an electric pole cast in the soil, and a spiral rod, the top of the second base plate is fixedly connected to a motor box, a motor is arranged inside the motor box, the top of the motor box is fixedly connected to a first fixing plate, the top of the motor box is provided with a first through hole, the output shaft of the motor extends to the top of the first fixing plate at the first through hole, the outer sleeve of the output shaft of the motor is provided with a fixing sleeve, the top of the first fixing plate is provided with a plurality of second through holes, and the first fixing plate is provided with a rotating ring at the second through holes. The present invention arranges a motor to drive the spiral rod to rotate, so that the spiral rod enters the soil, thereby loosening the soil on one side of the electric pole, so that it is more convenient and efficient to straighten the electric pole.

[0004] For another example, the patent with publication number CN109798018A discloses a utility pole straightening device and a straightening method, which belongs to the technical field of power maintenance equipment. The present invention comprises: a lower connecting seat, which is used to connect to a working surface; a telescopic support rod, one end of which is hinged to the lower connecting seat; a pushing mechanism, which is arranged on the telescopic support rod and is used to change the length of the telescopic support rod; and an upper connecting seat, which is hinged to the other end of the telescopic support rod and is used to connect to the utility pole. When the present invention is straightening the utility pole, the lower connecting seat is connected to a working surface such as the ground, the upper connecting seat is connected to the utility pole, and then the pushing mechanism is driven to extend the telescopic support rod, and the utility pole is pushed. The utility pole is straightened by relying on the pushing force, and the force conditions are better, which can greatly save manpower and will not cause the utility pole to sink.

[0005] In the prior art such as the above-mentioned patent, the pole erection device has the advantages of being more convenient, more efficient, having better stress conditions, and being able to greatly save manpower. However, the common disadvantage is that other tools are needed to measure whether the pole has returned to the vertical state during the actual operation. The equipment itself lacks a verticality detection system, which results in construction personnel having to rely on external measuring instruments or visually assess the vertical state of the pole. When there is no measuring equipment in the field or in a low-light working environment, this technical limitation will cause the problem of subjective errors in visual judgment. What is more serious is that the inclination of the pole that is not discovered in time will have a cumulative effect in the later stage, and the accelerated inclination will require the straightening operation to be repeated, thereby wasting manpower and material resources.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-Figure 10 A cement pole maintenance and straightening device provided by an embodiment of the present invention is used for straightening cement poles with an inclination angle within 10°, including a fixed seat 1 and a mounting frame 2 that are fixedly connected to each other, and also includes a first arc-shaped push ring 3, which is horizontally slidably connected to the mounting frame 2, and a mounting seat 47 is slidably installed on the mounting frame 2. A locking assembly 49 is provided on the side of the mounting frame 2, and a driving mechanism 4 includes a first rack 41, which is slidably installed on the mounting frame 2, and its end is fixedly connected to the first arc-shaped push ring 3. A rotating shaft 43 is rotatably installed on the mounting seat 47, and a first gear 431 is fixedly installed on the rotating shaft 43. The first gear 431 is meshed with the first rack 41, and the rotating shaft 43 extends through one side of the mounting frame 2 and is fixed with a turntable 46, and the diameter of the turntable 46 is larger than the diameter of the first gear 431.

[0022] By rotating the turntable 46, the rotation of the turntable 46 drives the axle 44 of the first gear 431 to rotate, and then the axle 44 drives the first gear 431 to rotate, and the rotation of the first gear 431 drives the first rack 41 to move, and drives the first arc-shaped push ring 3 to move. Since the diameter of the turntable 46 is larger than the diameter of the first gear 431, the operator can push the pole to the vertical direction with less effort under the action of the lever principle.

[0023] There are two embodiments for the design of the second arc-shaped push ring 31, one of which is that a second rack 42 is slidably mounted on the mounting frame 2, the second arc-shaped push ring 31 is fixedly connected to the second rack 42, a wheel shaft 44 is rotatably mounted on the mounting seat 47, a second gear 441 is provided on the wheel shaft 44, the second gear 441 is meshed with the second rack 42, the first gear 431 is connected to the second gear 441 through a transmission assembly 45, the transmission assembly 45 includes a synchronous transmission belt 451 and two synchronous pulleys 452, and the two synchronous pulleys 4 52 are fixedly connected to the wheel axle 44 and the rotating shaft 43 respectively, the two synchronous pulleys 452 are connected through the synchronous transmission belt 451, a torque limiter 48 is installed between the second gear 441 and the wheel axle 44, the inner wall of the torque limiter 48 is fixedly connected to the rotating shaft, and the outer wall thereof is fixedly connected to the second gear 441, the arc portion of the second arc push ring 31 is kept in close contact with the pole, the sliding direction of the second arc push ring 31 is the same as the sliding direction of the first arc push ring 3, and the axis of the second arc push ring 31 is parallel to the axis of the first arc push ring 3.

[0024] In the above technical solution, the first gear 431 rotates and drives the second gear 441 to rotate through the synchronous transmission belt 451. Figure 3 As shown, the second gear 441 rotates to drive the second rack 42 to move and drive the second arc-shaped push ring 31 to move. The first arc-shaped push ring 3 located above moves more than the second arc-shaped push ring 31 located below. Under the action of the torque limiter 48, the second gear 441 located below continuously switches between the rotation and stop states, so that the second arc-shaped push ring 31 and the first arc-shaped push ring 3 are always in contact with the pole and push the pole to move.

[0025] In another embodiment, if Figure 4 As shown, the second arc-shaped push ring 31 is fixedly connected with the slide rod 32. The second arc-shaped push ring 31 is horizontally slidably installed on the mounting frame 2 through an elastic member. The elastic member is used to push the slide rod to move. The elastic member is a second spring 321. One end of the second spring 321 is fixedly connected to the mounting frame 2, and the other end thereof is fixedly connected to the slide rod 32. The arc-shaped portion of the second arc-shaped push ring 31 is kept in tight contact with the pole under the action of the elastic member. The sliding direction of the second arc-shaped push ring 31 is the same as the sliding direction of the first arc-shaped push ring 3, and the axis of the second arc-shaped push ring 31 is parallel to the axis of the first arc-shaped push ring 3.

[0026] A telescopic rod, one end of which is rotatably connected to the mounting frame 2, and the other end of the telescopic rod is rotatably connected to a rotating portion 52, wherein the rotating portion 52 has an arc-shaped chamber, a fixed arc plate 51, which is fixedly connected to the rotating portion 52, a movable arc plate 511, which is slidably connected to the rotating portion 52, the axial direction of the movable arc plate 511 is the same as the axial direction of the fixed arc plate 51, and the movable arc plate 511 can be locked on the rotating portion 52 at any position during the sliding process through a locking element, a rotating cylinder 53, which is rotatably connected in the arc chamber, and a positioning rod 54 is axially slidably connected in the rotating cylinder 53, one end of the positioning rod 54 is in sliding contact with the arc bottom wall of the arc chamber, and a positioning hole is provided in the middle of the arc bottom wall.

[0027] In the above technical solution, Figure 3 As shown, since the rotating cylinder 53 is rotatably installed in the U-shaped shell, and a counterweight block 55 is fixed at the lower part of the rotating cylinder 53, the rotating cylinder 53 always maintains a vertical downward state under the action of gravity. At this time, the through hole below the rotating part 52 is not facing the telescopic end of the rotating cylinder 53, so the telescopic end cannot be extended. When the pole is straightened to the vertical state, since the axis of the rotating part 52 is parallel to the axis of the pole, the through hole below the rotating part 52 faces the telescopic end of the rotating cylinder 53. At this time, the telescopic end of the rotating cylinder 53 extends out of the U-shaped shell, and the extension of the telescopic end drives the first magnet block 66 to move downward.

[0028] The locking member 6 includes a third gear 61 and a fourth gear 62 rotatably mounted on the mounting frame 2, the third gear 61 meshes with the fourth gear 62, the third gear 61 has a larger diameter than the fourth gear 62, the fourth gear 62 is transmission-connected to the rotating shaft 43 via a spline, a friction disc 63 is coaxially fixedly mounted on the third gear 61, a locking rod 64 rotatably mounted on the mounting frame 2 is arranged above the friction disc 63, a V-shaped groove is provided at the other end of the locking rod 64, a rubber 65 is fitted and fixed on the inner wall of the V-shaped groove, a chamfer is provided on the edge of the friction disc 63 for use with the V-shaped groove, the locking member 6 also includes a first magnet block 66, the first magnet block 66 is fixed to the end of the positioning rod 54, and can pass through the lower through hole with the positioning rod 54, a second magnet block 67 is fixed to the end of the locking rod 64 close to the through hole, and a counterweight block 55 is fixed to the outer surface of the rotating cylinder 53.

[0029] The telescopic end extends to drive the first magnet block 66 to move downward to the effective adsorption position, and adsorbs the second magnet block 67 through magnetic force, and then the second magnet block 67 drives the locking rod 64 to rotate along the rotating installation point until the second magnet block 67 contacts the first magnet block 66, and then the V-shaped groove at the other end of the locking rod 64 moves downward, and then the rubber 65 contacts and approaches the friction disk 63. Under the action of friction force, the friction disk 63 is locked to rotate, and the friction disk 63 is subjected to force and fixes the third gear 61 to stop rotating. Since the diameter of the third gear 61 is much larger than that of the fourth gear 62, the fourth gear 62 is locked to rotate under the action of the lever principle, and then the force is transmitted to the turntable 46 through the spline. After the operator feels the resistance, he can stop rotating the turntable 46. Under the action of the lever principle, the friction force between the rubber 65 and the surface of the friction disk 63 can prevent the trend of the pole moving in the opposite direction.

[0030] The locking assembly 49 includes a connecting plate 491 fixedly mounted on the side wall of the mounting frame 2, a limiting plate 492 fixedly mounted on the side wall of the connecting plate 491, a locking tongue 493 slidably mounted on the side wall of the connecting plate 491, a spring 494 fixedly mounted between the locking tongue 493 and the connecting plate 491, pushing the mounting seat 47 until the side wall of the mounting seat 47 fits with the locking tongue 493 and pushes the locking tongue 493 to slide toward the connecting plate 491, and then the side wall of the mounting seat 47 contacts the limiting plate 492, at which time the locking tongue 493 is reset under the elastic potential energy of the spring 494, completing the locking of the lateral movement of the mounting seat 47.

[0031] Working principle: before operation, the mounting seat 47 is in an unlocked state, at which time the first rack 41 and the first gear 431, the second rack 42 and the second gear 441 are in a non-engaged state, and the operator pushes the device to move through the universal wheel under the fixing seat 1 until the first arc-shaped push ring 3 contacts the inclined pole (the inclination angle of the pole is within 10°), and then adjusts the device, and the first arc-shaped push ring 3 and the first rack 41 are pushed to slide under the action of the pole until the second arc-shaped push ring 31 contacts the pole. Since the movement directions of the first arc-shaped push ring 3 and the second arc-shaped push ring 31 are consistent and the axis The lines are all vertical, so the first arc push ring 3 and the second arc push ring 31 are both in contact with the side wall of the pole, and the line connecting the centers of the first arc push ring 3 and the second arc push ring 31 is parallel to the axis of the pole. Then, the universal wheel is retracted and the device is fixed to the ground, and the fixed arc plate 51 fixed on the rotating part 52 is adjusted until the inner arc surface of the fixed arc plate 51 is in contact with the pole, and then the movable arc plate 511 on the other side is slid to fit the pole and lock the movable arc plate 511, so that the balancing assembly 5 is in a state of being fixed on the pole, and the axis of the rotating part 52 is consistent with the axis of the pole.

[0032] Push the mounting seat 47 until the side wall of the mounting seat 47 fits against the locking tongue 493 and pushes the locking tongue 493 to slide toward the connecting plate 491. Then the side wall of the mounting seat 47 contacts the limiting plate 492. At this time, the locking tongue 493 is reset under the elastic potential energy of the spring 494, completing the locking of the lateral movement of the mounting seat 47. At this time, the first rack 41 is meshed with the first gear 431, and the second rack 42 is meshed with the second gear 441. The movement of the axle 44 of the first gear 431 does not drive the fourth gear 62 to move. The fourth gear 62 is always connected to the axle 44 of the first gear 431 through a spline.

[0033] The rotating disk 46 is rotated, and the rotation of the rotating disk 46 drives the axle 44 of the first gear 431 to rotate, and then the axle 44 drives the first gear 431 to rotate, and the rotation of the first gear 431 drives the second gear 441 to rotate through the synchronous transmission belt 451, and the rotation of the first gear 431 and the second gear 441 drives the first rack 41 and the second rack 42 to move, and drives the first arc push ring 3 and the second arc push ring 31 to move. Since the diameter of the rotating disk 46 is larger than the diameter of the first gear 431 and the second gear 441, the lever principle is used to make Workers can push the pole to move in the vertical direction with less effort. The first arc-shaped push ring 3 located above moves more than the second arc-shaped push ring 31 located below. Under the action of the torque limiter 48, the second gear 441 located below continuously switches between the rotation and stop states, so that the second arc-shaped push ring 31 and the first arc-shaped push ring 3 are always in contact with the pole and push the pole to move. In this process, the fourth gear 62 rotates under the action of the spline force transmission, and drives the third gear 61 meshing with it to rotate, and the third gear 61 drives the friction disk 63 to rotate.

[0034] The rotating cylinder 53 is rotatably installed in the U-shaped shell, and a counterweight block 55 is fixed at the lower part of the rotating cylinder 53, so the rotating cylinder 53 always maintains a vertical downward state under the action of gravity. At this time, the through hole below the rotating part 52 is not facing the telescopic end of the rotating cylinder 53, so the telescopic end cannot be extended. When the pole is straightened to the vertical state, since the axis of the rotating part 52 is parallel to the axis of the pole, the through hole below the rotating part 52 faces the telescopic end of the rotating cylinder 53. At this time, the telescopic end of the rotating cylinder 53 extends out of the U-shaped shell, and the extension of the telescopic end drives the first magnet block 66 to move downward to the effective adsorption position, and adsorbs the second magnet block 67 through magnetic force, and then the second magnet block 67 The locking rod 64 is driven to rotate along the rotating installation point until the second magnet block 67 contacts the first magnet block 66, and then the V-shaped groove at the other end of the locking rod 64 moves downward, and then the rubber 65 contacts and approaches the friction disk 63. Under the action of the friction force, the friction disk 63 is locked to rotate, and the friction disk 63 is subjected to force and fixes the third gear 61 to stop rotating. Since the diameter of the third gear 61 is much larger than the fourth gear 62, the fourth gear 62 is locked to rotate under the action of the lever principle, and then the force is transmitted to the turntable 46 through the spline. The operator can stop rotating the turntable 46 after feeling the resistance. Under the action of the lever principle, the friction between the rubber 65 and the surface of the friction disk 63 can prevent the pole from moving in the opposite direction.

[0035] Then the operator can carry out the filling repair operation. After the pole is fixed and stable, the operator presses down the end of the locking rod 64 with the second magnet block 67, pushes the telescopic end of the rotating cylinder 53 into the rotating part 52, removes the arc-shaped ear plate, and then releases the fixing seat 1 from the ground, releases the universal wheel and moves the device away from the pole to complete the maintenance and straightening operation.

[0036] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
